Improvement in pumps

MIDDLETOWN, INDIANA.

Letters Patent No. 102,199, :lated April 19, 1870.

To all whom it may'concern:

Be it known that I, BENJAMIN F. GUs'rlN, of Middletown, in the county of Henry and State of Indiana, have invented a new and useful Improvement in Oombined Lifting and Force-Pumps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings of the same which make part of this specication, and in which- Figure 1 represents an elevation of a pump, embracing my improvements.

Figure 2 represents a vertical section, showing the parts arranged as an ordinary lifting-pump.

Figure 3 represents a similar section, showing the several parts arranged for a force-pump.,

Figure 4 represents a top view of the pump.

My invention relates to the construction of an ordinary lifting-pump in such manner that it may be converted into a force-pump at will, and consists in dividing the stock of the pump into an upper and lower chamber by means of a water-tight core, and providing said core with an opening, which unites the two chambers and a suspended valve, which, when closed with the core, separates the two chambers so as to cut olf communication with the upper chamber and put the lower one in communication with an auxiliary air-chamber, from which the water is expelled .by the force of the air therein against the const-ant supply of the water from the lifting-pump, so that the latter may be converted a forcing hydrant, and used with a hose in case of a re, or for other purposes.

In the accompanying drawings- Arepresents the pump-stock fitted with a supporting-plug, B, at its lower end, through openings` in which the water enters, and is held therein by a valve, C, at its top. It is divided near the middle of its length intoan upper and a lower chambeIjD and E, and is provided with the usual valved sucker G, han- ?"dle H, and egress-spout I.

'-1The connecting-rod J, of the valved sucker, passes through a central opening in the division plug P, and

is packed in any suitable manner.

The two chambers of the pump thus formed communicate with each other through an opening, a., in the division plug P, but may be separated so as to cut oif this communication by means of a. suspended valve, K, the connecting-rod Q of which passes through the opening a in the plug P, and up through an opening, bin the cap It, to which it is held from falling too far by a pin, o, and locked when raised up to close the -opening in the division plug P by a latch, el, pivoted to the cap It, as shown in fig. 4.

The suspended valve K is made conicaland its position is sufciently far below the division plug P to clear the opening, but when drawn up by its rod Q it is made to fit a correspondingly-shaped mouth of the communicating opening a, so as to seal it.r

When this valve is open the sucker lifts the water and discharges it through thespout I, but, when closed, the chamber E is put in communication with an auxiliary air-chamber, L, arranged on the outside of the pump-stock A by means of a pipe, M, communicating with the lower end of said air-chamber, and the upper end of the lower pump-chamber E.

This air-chamber is located near the top of the pumpstock, and secured thereto by any suitable means. It is provided with an ingress-valve, f, at its lower end, a stop-cock, N, and an legress-nozzle, O, to which a hose may be attached Whenever desired. e

The water is pumped into this chamber through the connecting-pipe M and valve f, `so'as to compress the air therein, and, when then faucet N is open, the water is forced out through the hose, and will be thrown a distance equal to the pressure of the air in the chamber L, aided by the constantly supplying-stream from the lower chamber E.

The division plug P is tted tightly upon a seat, l1, within the chamber of the pump, and secured by a screw, so that it may be removed if desirable.

Having described my invention,

I claim- 1. The division plug P, in combination with the upper and lower chambers D lIl of the pump, andthe suspended valve K, constructed and operating substantially as herein described and shown.

2. The auxiliary air-chamber L, arranged on the outside of the pump, and communicating with the lower water-chamber E thereof, in the manner and for the purpose herein shown and described.

3. The sealing-valve K of the lower water-chamber- E, united to and operated by means of a connectingrod, Q, held up when closed by the latch (l, and supported when open in the manner and for the purpose herein shown and described.

4. An ordinary lifting-pump which may be converted into a forcing-pump or hydrant by means of the division P and valve K, operated as described. v

5. The combination in a lifting-pump of the division plug P, the upper and `lower water-chambers D E, the communicating opening-a, the 'suspended valve K with its opening and closing connecting-rod Q, the auxiliary air and water-chamber L with its connecting-pipe M, nozzle O, and stop-cock N, the Whole arranged, construeted, and operating as herein shown and described B.
